Guest post by Chance Marshall, University of Wyoming Extension Educator, Fremont County

Times are changing and the cost of current sources of energy use are continuing to rise for landowners in Wyoming. University of Wyoming Extension is in the process of exploring alternative energy applications that could save money but still be dependable for their clientele.

The Wyoming Renewables website provides a wealth of information on many sources and applications for alternative energy in Wyoming.

Typical renewable energy systems that are used are: biomass, geothermal, hydroelectric, solar, and wind. Currently 87.5% of Wyoming’s energy comes from coal, however, alternative methods (solar, small hydro, wind) are growing quickly and account for about 11.2% of the state’s electricity production.

By the year 2100, it is speculated that solar energy systems could account for the majority of energy production in the United States. Many wonder why solar may be the answer and not other methods (i.e. wind)? The reasons are simple. Solar is easy to install, energy from the sun is reliable throughout most of the country, and due to technological improvements, installation costs are decreasing while energy capture continues to increase. Other methods are often more site-specific and less reliable.

Currently, UW Extension Educators are exploring the applications of do-it-yourself solar-thermal stock tanks during the Wyoming winter season as an alternative to electric tank heaters. These tanks are designed to run solely off the sun’s energy. These custom tanks are made with easily obtainable materials (lumber, insulation, etc.) and no electricity, solar panels, or batteries are necessary. Commercially made solar-thermal stock tanks have proven to be effective but come with a hefty price tag. The goal of the project is to determine if a livestock owner in Wyoming can create an affordable winter watering system that will save money but still keep water from freezing. Initial results are still pending, but stay tuned for more information.

Please look through my presentation on the topic of alternative energy for the 2016 WESTI Ag Days and don't hesitate to call me with any questions.
